I was wondering when this spy unit was gonna get some brains. Now that action spy sequel IRIS 2 has cast all its field agents and enemy spies and possibly-maybe-doubling-crossing-agents, it finally adds an analyst to the roster: Baek Sung-hyun has joined the cast as a young genius hacker without whom NSS wouldn’t go ’round.

It’s a pretty funny character description if you still see Baek Sung-hyun as Lee Min-jung’s dumb little bro in Big. He was adorable, but epically dim – perhaps adorable because of it, but in any case, a box of rocks for brains. But he can certainly pull off a drastic transformation — he’s played dark characters before (White Christmas), and as a former child actor, he’s had more experience than the average 23-year old.

In IRIS 2 he’ll play an extremely gifted brainiac, and NSS teammates with field agents Lee Da-hae and Yoon Doo-joon. The three of them will work under team leader Jang Hyuk, who apparently trained them all. His character will be the speedy source of information within the agency, and also the mood-keeper-upper of the group, promising to bring some much-needed levity to the NSS set. He’s also known as a problem-solver to the rest of the characters, which is potentially really funny. It’d be awesome if they treated him like an Answer Man, for everything from How do I save the world? to How do I break up with my girlfriend?

He’ll hopefully have some delightful character quirks, because I don’t want to rain on this team’s parade or anything, but he’s the first member who doesn’t sound like a total bore. Not that badass is boring, but in a spy drama, it’s kinda like having a pulse.

I always like a spy drama with a techie buddy to backup the field agents. The hacking theme is the reason why I love So Ji Sub’s Ghost. I hope there would be lots of hacking done on this drama ‘coz that will really turn me on. It makes the spying more interesting.

I first saw him in ‘That Fool’ as the actress’ brother. I was very surprised. A good-looking kid who can act and be in sync with more experienced actors (let alone a monster like Hwang Jung Min). I think he should definitely be given more and bigger roles. He has potential, let’s not waste it (which I am sorry to say, ‘Big’ did, but then that trainwreck messed up a lot).

Very glad to see him here, although this won’t exactly showcase his acting very much, but at least he’ll have it in his credits and maybe gain some popularity from it.

I’ve only seen him in “Queen Insoo” and he was very good in that – he played two different roles and I think successfully manage to differentiate between the two (he played both father and son e.g. Insoo’s husband and second son).

Yeaaa! I really agreed with you ~ I’ve watched him with actress Park Shin Hye in ‘Stairway to Heaven’ about five or six years ago! They was doing great job together, yups. As a matter of fact, I really would like to see him with Park Shin Hye reunite together in a new rom-com drama somedaaaay!

He was the first love I had that was actually kind of my age growing up watching korean dramas, ha. He was the child actor for the protagonist of Hae Shin (Emperor of the Sea) and he was so heartbreaking in it.
